Specification of Letters Patent. fateii'ted Sept. 2?, 115 210 To all whom it may coecern:

Be it known that 1, Joe KovAR, a citizen of the United States, end resident of Coupland, in the county of Williamson and State of Texas, have invented a new and improved Incubator, of which the following is a full, clear, and exact description.

hi ihveptiflli relates to an automatic heat regulating unit, and more particularly a device of this nature primarily intended to be associated with an incubator.

in connection with incubators, it is a well appreciated fact that considerable diiliculty has been experienced in providing s heating unit which might be entirely automatic in operation, and which would permit of a minimum of variation of heat within the incubator, and in which enytendency on: the part of the heating medium to cause the temperature to rise or drop beyond a, yoredetermined point would he materially counteracted.

/Vith this in view, i have constructed e heating system more particularly intended for use in connection with incubators, but not necessarily limited to this adoption, and by means of which he temperature of the incubator or other device with which the system is associated, wiil he constantly maintained at a predetermined point.

A "further object of my invention, is the construction of a device of this nature which shall be extremely simple in construction, and hence economical to mehufectui'e, as well as to operate.

A still further object of my invention is the construction of a heating system of the type specified which shall be entirely auto matic in operation, so that e mihimum of attention is required Further objects of my invention will op pear in the annexed specification end olmwings, which letter represent one practical embodiment of my invention, end in which Figure 1 is e side view of so iiiculoetoi having a heating system constructed in sccordeuce with my invention eppiied thereto,

Fig. '2 is o fragmentary sectional view taken along the line 2-2 of i,

Fig, 8 is a side view of certain of the ports forming the system.

Fig, l is e sectional side view along the line aii of Fig, 5, end

Fig. is a plan view of the device with the top removed.

In these views the reference numeral 10 indicates the side walls and hose of the incubator, which may be properly heat insuiated, as at 11, and which are supported by suitable legs, as at A top, or lid of convenient construc tion is associated with the incubator, thus providing a top conveniently also embracing a heat insulated portion 13, provided with a sight opening 1 1, and preferably e layer of transparent material 15, below said top, and detached theve'ieom so that the top may he removed without exposing the interior of the incubator or other device, to a sudden chill.

The incubator, however, preferably includes a cent-rally extending partition 16 formed with an opening 1? ,thus providing an incubating space 18 brooding space 19, the chicks, subsequent hatched, dropping through into the breeding space 19.

My hosting" system new couvenientiy ineludes, o. pipe or conduit 20, preferably disposed edicceiit edges of the incubating space in which position, it is suppoited any suitable brackets 21.

The pipe 20 is preferahly formed with an extended portions 22, which. isedepted to directly over-lie e lamp or other suitable the opening 17 heating element :23, so that the fluid within this conduit may he zoroperiy heated. An inlet, in form oi ough 9A is provided at one point in the conduit 20, an outlet pipe being; conveuiv y positioned at a point substantially oppo trough 2%}.

It is new to d that the trough is piei'eceh y at A A it slightly highe then the conduit so Wtt'iiil introduced into the trough will edily flow into the conduit. it wiil also ice seen that e bracket, 01 other supporting :28 is coovenientiy essocisoed with the outiet to this to their being the upper side outlet pipe at a height corresponding to the J.

die

face of one of the side walls of the incu: bator, and adjacent the thermostat positioned within the same, and this latter lever is rockingly retained in position by means of a forked bracket 3%, vertically adjustable as at 33 for a purpose hereinafter more fully specified, to which the lever 31 is rockingly secured. as at 3 lit will. be not-ed that the lever 81 extends both. sides of its point. of support 34, and a counter-weight is conveniently associated with this lever, adjacent one of its ends, The opposite end of the lever 31 extends: to a point adjacent and above the inlet trough 24, it being noted that the outer end of the lever 29 conveniently engages the lever 31, as at 36, thus permitting the thermostet 28 to move the same, e stop 37 being utilized to limit the upward movement of he lever A. source of water supply, such. as a desk 8 is movehly supported. as at 39, upon a lnCliB positioned adjacent the trough wire New in operation, will. be understood, assumin '1. has risen. above the tempera which the parts have been rate, that the thermostat 28 will expend, mus depressing the outer end of the lever 29 associated therewith. lhis action will result, by virtue of the connection 36-, in depressing of the lever 31 in turn perini downwardly JQVS the trough 24 to ahorirental level, which the trough d1 will feed through re pipe i2, into the trough 2- consequently introducingcold water into the conduit This obviously will instantly lower the temperstu I it being noted, has been redcscribod, that on amount of hot water, equal to the amount of cold water introduced into the con will be displaced therefrom through the outletpipe The heating will continue to heat the fluid element within the conduit 20, It will be obvious that upon the temperature falling below the which is to be maintained, that the intrude t ct cold water into the conduit the feet that the thermostet e 1e feeding pipe 452 to swing i528 will become contracted, thus raising the outer end of the lever 29, this lever raising" the lever 31, and consequently the feed pipe 42.

t will be obvious that the temperature which is to be maintained may be adjusted by virtue of the bracket 32, and the support 80. These two members permit of the adjustment of the heightof the pivot of the lever 31, together with the height of the feeding pipe 42, which will obviously produce the result desired.

From the foregoing it will be understood that I have constructed e heating medium more particularly adapted for use in connection with an incubator, but not necessarily limited to this adaption, and in which numerous modifications of structure might readily be resorted to without in the least depart-- ing from the spirit of my invention, which I claim as;--

1. A heating system, including a conduit, a thermostat, means for heating fluid without the conduit, a manually operable overflow pipe connected with said conduit, an intake trough connected with said conduit, a second trough, a reservoir adapted to maintain fluid at a constant level in the second trough, a flexible. pipe extending from said second trough and having its outer end overlying said intake trough, a thermostat lever connected to and moved by said thermostat, a second lever, and means for pivotallymounting said second lever, said first named lever being connected with said second lever, and controlling the movement thereof, said second lever contacting with the flexible pipe, whereby the latter will be moved proportionate to the degree of movement of the thermostat.

2. In a heating system, a liquid conduit, means for heating the liquid of the conduit, an intake trough communicating with the conduit, a cold water receptacle having a flexible tube extending above said trough, a thermostat, a pivoted lever operated by the thermostat, an adjustable support, a second lever pivoted intermediate of its ends in the said support and with which the free end of the first lever has a loose connection adjacent its pivot, one end of the second lever having a weight thereon and its other end extending below and in engagement with the pipe of the receptacle, and means for limiting the upward movement of said second lever.
